Ram air turbine (RAT) pump, by transforming the mechanical energy into hydraulic energy, can be used to control the aircraft rudder in emergency situation. Its performance of rapid response is critical to ensure the aircraft's safety. Exposed to low-temperature atmosphere for long time, the high viscosity of hydraulic oil will hinder the rapid start of the hydraulic pump, and an effective method for this problem is to introduce the high-pressure oil into aircraft RAT pump from the main hydraulic system. Taking RAT pump as research object, this paper explores the calculation method of minimum temperature control orifice for the RAT pump. First, it explains the thermal insulation theory of the RAT pump which is equipped with temperature control orifice in standby mode and proposes an algorithm of the orifice. Second, it establishes RAT pump's thermodynamic model and deduces the calculation formula of the orifice's diameter. Next, it establishes temperature control system's thermodynamic model with MATLAB and calculates the results. Finally, it verifies the correctness of the algorithm through simulation calculation, and energy saving effect is remarkable.
